Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a coarse crusher for pharmaceutical use. Background Technology

[0002] Coarse grinding of medicinal materials refers to processing Chinese medicinal materials using specific equipment or processes to achieve a relatively coarse particle size. This grinding method is usually used for the preliminary processing of Chinese medicinal materials to facilitate subsequent processing or decoction.

[0003] Coarse crushing, as one processing method, mainly involves breaking medicinal materials into larger particles through mechanical or manual force. For example, the Chinese utility model patent disclosed in publication number CN218945238U, "A High-Efficiency Two-Stage Crusher," uses a coarse crushing component and a fine crushing component to crush medicinal materials sequentially. The crushing gears on the two first rotating shafts are staggered to intercept the less easily crushed medicinal materials, separating them from the more easily crushed parts and avoiding repeated crushing of the easily crushed materials, which would result in excessively small particles. However, when crushing medicinal materials using this method, the materials need to be fed into the crusher through an inclined feed inlet. As the materials enter the crusher through the feed inlet, they tend to accumulate at the inlet position, preventing them from sliding into the crusher on their own. The materials must be manually pushed into the crusher. This feeding method can easily cause the operator's hands to be caught in the materials and get caught in the crusher, resulting in injury and posing a safety hazard during the crushing and feeding process. Utility Model Content

[0004] The purpose of this invention is to provide a coarse crusher for pharmaceutical use, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pharmaceutical coarse crusher includes a crushing chamber. A bracket is fixedly installed on the outside of the crushing chamber. A first motor is fixedly installed at the bottom inside the bracket. The first motor is electrically connected to a controller on the crushing chamber via a connecting wire. A transmission mechanism is provided on one side of the crushing chamber. The input end of the transmission mechanism is drivenly connected to the output end of the first motor. Two crushing rollers are movably installed on one side of the crushing chamber, and one end of each crushing roller is drivenly connected to the output end of the transmission mechanism. A feeding hopper is also fixedly installed on one side of the crushing rollers in the crushing chamber. A protective cover is fixedly installed at the lower end of the feeding hopper. A pushing mechanism is provided inside the feeding hopper. The pushing mechanism includes four sprockets, with two sprockets forming a group and movably installed on one side of the bottom of the feeding hopper. A curved plate chain is movably connected between the two sprockets. A sliding rod is provided on one side of the curved plate chain. The sliding rod is movably installed on one side of the curved plate chain via a connecting piece. Two push rods are movably connected between the two sliding rods.

[0007] As a further preferred embodiment of this utility model, two guide rails are fixedly installed on both sides of the feed hopper, and a first sliding groove is provided in the feed hopper located between the two guide rails. The sliding of the slide rod can be made more stable by setting the two guide rails.

[0008] As a further preferred embodiment of this utility model, multiple bearing seats are fixedly installed on both sides of the bottom of the feed hopper, and a rotating shaft is rotatably installed in two bearing seats on the same side. The two rotating shafts are movably connected by a universal joint, and the ends of the two rotating shafts away from the universal joint are fixedly connected to the corresponding sprockets. Since the feed hopper is designed with a tapered structure to facilitate the entry of materials into the crushing box, the connection between the two rotating shafts by the universal joint allows the two sprockets on the same side to rotate synchronously.

[0009] As a further preferred embodiment of this utility model, the connecting piece has an L-shaped structure, a connecting shaft is fixedly installed on one side of the connecting piece, a displacement groove is rotatably installed on the outer side of the connecting shaft, an installation shaft is fixedly installed at the center of the bottom of the connecting piece, and the bottom of the installation shaft is inserted into the curved plate on one side of the curved plate chain and fixed by a snap ring.

[0010] As a further preferred embodiment of this utility model, a displacement groove is provided inside the slide rod, and two second slide grooves are provided above the displacement groove. A connecting block is fixedly installed on the slide rod between the two second slide grooves. The lower part of the slide rod is inserted and installed on the bearing through the displacement groove. A retaining spring is installed on the connecting shaft on one side of the slide rod. The second slide grooves are slidably installed on the corresponding guide rails, and the connecting block is slidably installed in the first slide groove. Through the arrangement of the bent plate chain, connecting piece, connecting shaft, and bearing, the displacement groove can be used to make the lateral reciprocating motion along the feed hopper.

[0011] As a further preferred embodiment of this utility model, each of the two push rods has a connecting groove at both ends. The connecting grooves at opposite ends of the two push rods are rotatably connected by a connecting rod, while the connecting grooves at the other ends of the two push rods are rotatably mounted on corresponding connecting blocks. Flexible push plates are fixedly connected to the bottom of the two connecting grooves. The two connecting grooves are driven to reciprocate by two sliding rods, which can cooperate with the flexible push plates to push the medicinal materials in the feed hopper into the crushing box.

[0012] As a further preferred embodiment of this utility model, a second motor is fixedly installed on one side of the protective cover. The second motor is electrically connected to the controller on the top of the crushing box via a connecting wire, and the output end of the second motor is fixedly connected to one of the sprockets. The second motor can drive two sets of sprockets and curved chain for transmission operation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The pharmaceutical coarse crusher described in this utility model has a pushing mechanism installed in the feed hopper. The pushing mechanism consists of two sets of sprockets, a bent plate chain, a slide bar, a connecting plate, a push rod, a second motor, and other components. The bent plate chain drives the connecting plate and the slide bar to move laterally back and forth, so that the two push rods, together with the flexible push plate, automatically push the medicinal materials in the feed hopper into the crushing box, thus eliminating the need for manual feeding and ensuring the safety of personnel.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-6 As shown, the present invention provides a pharmaceutical coarse crusher, including a crushing box 1, a bracket 2 fixedly installed on the outside of the crushing box 1, a first motor 3 fixedly installed at the bottom inside the bracket 2, the first motor 3 being electrically connected to a controller on the crushing box 1 via a connecting wire, a transmission mechanism 4 being provided on one side of the crushing box 1, the input end of the transmission mechanism 4 being connected to the output end of the first motor 3, two crushing rollers 5 being movably installed on one side inside the crushing box 1, and one end of the crushing rollers 5 being connected to the output end of the transmission mechanism 4, a feeding hopper 6 being fixedly installed on one side of the crushing rollers 5, a protective cover 7 being fixedly installed at the lower end of the feeding hopper 6, a pushing mechanism 8 being provided inside the feeding hopper 6, the pushing mechanism 8 including four sprockets 9, two sprockets 9 being a group and movably installed on one side of the bottom of the feeding hopper 6, a curved plate chain 10 being movably connected between the two sprockets 9, a sliding rod 11 being provided on one side of the curved plate chain 10, the sliding rod 11 being movably installed on one side of the curved plate chain 10 via a connecting piece 12, and two push rods 13 being movably connected between the two sliding rods 11.

[0024] like Figures 2-3 As shown, two guide rails 14 are fixedly installed on both sides of the feed hopper 6. The feed hopper 6 located between the two guide rails 14 has a first sliding groove 15. The setting of the two guide rails 14 makes the sliding of the slide rod 11 more stable. Multiple bearing seats 17 are fixedly installed on both sides of the bottom of the feed hopper 6. The two bearing seats 17 on the same side are respectively rotatably installed with rotating shafts 18. The two rotating shafts 18 are movably connected by a universal joint 19. The ends of the two rotating shafts 18 away from the universal joint 19 are respectively fixedly connected to the corresponding sprockets 9. Since the feed hopper 6 is designed with a tapered structure to facilitate the entry of materials into the crushing box 1, the connection between the two rotating shafts 18 by the universal joint 19 can make the two sprockets 9 on the same side rotate synchronously.

[0025] like Figures 3-5As shown, the connecting piece 12 has an L-shaped structure. A connecting shaft 22 is fixedly installed on one side of the connecting piece 12. A displacement groove 24 is rotatably installed on the outside of the connecting shaft 22. An installation shaft 21 is fixedly installed at the center of the bottom of the connecting piece 12. The bottom of the installation shaft 21 is inserted into the bent plate on one side of the bent plate chain 10 and fixed by a snap ring. A displacement groove 24 is opened in the slide rod 11. Two second slide grooves 25 are opened on the slide rod 11 above the displacement groove 24. A connecting block 26 is fixedly installed on the slide rod 11 between the two second slide grooves 25. The lower part of the slide rod 11 is inserted into the bearing 23 through the displacement groove 24. A snap ring is clamped on the connecting shaft 22 on one side of the slide rod 11. The second slide groove 25 is slidably installed on the corresponding guide rail 14. The connecting block 26 is slidably installed in the first slide groove 15. Through the arrangement of the bent plate chain 10, the connecting piece 12, the connecting shaft 22, and the bearing 23, the displacement groove 24 can be used to make the lateral reciprocating motion along the feed hopper 6.

[0026] like Figures 3-6 As shown, each of the two push rods 13 has a connecting groove 27 at both ends. The connecting grooves 27 at opposite ends of the two push rods 13 are rotatably connected by a connecting rod 28, while the connecting grooves 27 at the other ends of the two push rods 13 are rotatably mounted on the corresponding connecting blocks 26. Flexible push plates 20 are fixedly connected to the bottom of the two connecting grooves 27. The two connecting grooves 27 are driven to reciprocate by the two sliding rods 11, which can cooperate with the flexible push plates 20 to push the medicinal materials in the feed hopper 6 into the crushing box 1.

[0027] like Figures 1-2 As shown, a second motor 16 is fixedly installed on one side of the protective cover 7. The second motor 16 is electrically connected to the controller on the top of the crushing box 1 through a connecting wire, and the output end of the second motor 16 is fixedly connected to one of the sprockets 9. The second motor 16 can drive the two sets of sprockets 9 and the bent plate chain 10 for transmission operation.

[0028] It should be noted that this utility model is a coarse crusher for pharmaceutical use. When crushing medicinal materials, the medicinal materials can be placed into the feed hopper 6. Then, the controller on the top of the crushing chamber 1 synchronously starts the first motor 3 and the second motor 16. The first motor 3, in conjunction with the transmission mechanism 4, drives the crushing roller 5 in the crushing chamber 1 to rotate. At the same time, the second motor 16 drives one of the sprockets 9 to rotate, which in turn drives the sprocket 9 on the other side of the bottom of the feed hopper 6 synchronously through two rotating shafts 18. The two sprockets 9 are connected to the two sprockets 9 on the other side of the bottom of the feed hopper 6 through a bent plate chain 10. This allows the two sprockets 9 at the bottom of the feed hopper 6 to drive the corresponding connecting plates 12 to reciprocate through the bent plate chain 10. Thus, the connecting plates 12 drive the sliding rod 11 to move laterally along one side of the feed hopper 6 through the connecting shaft 22 and the bearing 23. This causes the slide bar 11 to slide on the corresponding guide rail 14 via two second slide grooves 25 on one side. Thus, the two slide bars 11 drive the corresponding push rods 13 to move towards the crushing box 1 via the connecting block 26 on one side. This causes the two push rods 13 to be movably connected via the connecting rod 28 and cooperate with the flexible push plate 20 to feed the medicinal materials in the feed hopper 6 into the crushing box 1 for crushing. When the bent plate chain 10 drives the connecting plate 12 to move to one of the sprockets 9 and turns to change direction, the connecting shaft 22 can rotate in the displacement groove 24 of the slide bar 11 via the bearing 23, so that the slide bar 11 temporarily stops on one side of the feed hopper 6. After the connecting plate 12 has changed direction through the slide bar 11, the connecting plate 12 continues to rotate in the displacement groove 24 via the connecting shaft 22 and drives the slide bar 11 to move back. Then, the medicinal materials can be put into the feed hopper 6 again, and the operation can be repeated.

[0029] The reason why the two push rods 13 are connected by the connecting rod 28, and one end of the two push rods 13 is also rotatably connected to the corresponding connecting block 26 through the connecting groove 27, is that the feed hopper 6 has a structure that gradually shrinks towards the crushing box 1. This allows the two push rods 13 to adaptively adjust their angles when moving, thus ensuring that the medicinal materials in the feed hopper 6 can be pushed into the crushing box 1.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
